Hi! I own a Realforce 87U all-45g.
I do a lot of typing for work (not coding however), and after going through MX browns, reds, and blues, I found that Topre switches were my destiny with their gentle and bassy "thock" sounds and incredibly smooth linear feel.
Now I'm looking for keycaps to personalize this Merc of a keyboard to my liking. I have ordered several 3D-printed keycaps from Shapeways, which many were concerned about in terms of their details and somewhat crude surface, so I'll post pics of them once they arrive. In the meantime, I'll be checking the marketplace here for Topre keycaps
Cheers and happy typing!
